It is desirable that the is or the rollers be disposed in parallelism 1with the diameter of the tire and this is accomplishedpin or rod 22restingon one by means of th 1s shown in Fig, 1, and of course this rodor pin will have to be adjusted to accommodatethe diameter otthe tire bymeans of the adjustable sleeve 19 as heretofore detailed.

It is desired 'to point out some other features of advantage andutility. The extension 6 is provided so that the handle 8 may have areater throw by being closer to the center of the tire. This handle 8abuts the side of the tire when the rollers 10 are swung ast dead centeras shown in Fig. 1, and tlius the parts are locked in this posi- Thechannels 18 inthe rollers 10 function as heretofore stated, but alsotend to resist the accidental withdrawal of the roller when disposed inthe tire, and they also are adapted to receive ribs projecting inwardlyfrom some makes of tires.

It is thought that the construction, operation, utility, and advantagesof this invention will now be quite apparent to those skilled in thisart withouta more detailed descri tion thereof.

Tie present embodiment of the invention has been disclosed in detailmerely b way of example, since in actual practice 1t attains thefeatures of advantage enumerated as desirable in the statement of theinvention and the above description.

It will be apparent that changes may be made in the details ofconstruction, and in the combination and arrangement'of parts withoutdeparting from the spirit or scope not only allelism to each from theshank atan journale including a s of the invention as hereinafterclaimed or.

A tire spreader of the class described includin ,a shank, a pairof'bolts extending from t e shank laterally and in spaced arallelism toeach other, a handle exten ing angle thereto, apin extending laterallyfrom the handle in the same direction with theshank for 'engaging onebead of the tire, adjustable means for mounting said pin on said handle.

3. A tire spreader of the class described including a shank, a pair' ofbolts extending from the shank laterally and in spaced parallelism toeach other, from the shank at an angle thereto, a pin extendinglaterally from the handlein the same direction with the shank forengaging one head of the tire, adjustable means for said pin on saidhandle, rollers on said bolts. 4.
